[Amps] measure inrush

[John T. M. Lyles]

Happy new year to all the amplifier builders and experimenters with 
higher power RF here.

When I designed step start for commercial transmitters i used a clamp 
on Fluke current transformer, and connected it to a scope. There I 
could see the momentary inrush current scaled by 100 or 1000. As long 
as the CT wasn't saturated this worked well.

When I step start modified my SB220 years back,  I just used low 
value Resistors and noted that the plate voltage comes on for a 
fraction of a second at lower voltage before kicking up to max. The 
resistors didn't feel warm afterwards, so I believe it worked fine.
